  • Converts SD/HD/3G-SDI and stereo audio input signals to high quality USB 3.0 output.
    • Automatic input equalization – compensates for attenuation on the incoming signal and automatically equalizes cables for the following distances using 75 Ohm RG6 BNC cables:
      • 3G-SDI 1920x1080 @60Hz to 328 feet (100 meters).
      • HD-SDI 1280x720 @60Hz to 656 feet (200 meters).
      • SD-SDI 525i @60Hz and 625i @50Hz to 984 feet (300 meters).
    • Automatic output reclocking – reshapes and restores timing of digital video signal at output, eliminating high frequency jitter.
  • Compliant with UVC and UAC standards.
    • UVC protocol allows the host computer/laptop to set the parameters for the USB stream such as resolution, frame rate, and aspect ratio.
  • Supports resolutions to 1920x1080 @60Hz.
  • Independent HDMI loop-through allows the original full-quality source to be routed to monitors or other equipment.
    • Fixed resolution: 1920x1080 @60Hz.
  • Auto-detects 3G-SDI, HD-SDI, or SD-SDI format.
    • Supports SMPTE 259M-C, SMPTE 292M, SMPTE 424M, SMPTE 425M Level A and B video interfaces used for broadcast-grade video.
  • 3.5mm stereo audio input for microphone and output for use with headphones, powered speakers, or connection to an amplifier/receiver.
